Do not know how official this is but recent CAR reviewers have somehow found out that the Toyota FT-86 prototype / test mule spits out a global warming figure of 160g/km Co2. I don't see why the Scion FR-S would be different. Not sure if production models will change but that is a place to start.

I know nothing about emission ratings (don't care sorry) how does this compare to the competitors? Post up competitors ratings!!
